This metric totals the BTC balances of entities in the 10–100 BTC range, after addresses attributed to a common controller are combined. It isolates this middle balance band rather than including every entity above 10 BTC.
More BTC in this range means the cohort’s supply has expanded; less means it has contracted. Holdings peaked near 3.262 million BTC on October 17, 2023 and stood around 3.080 million BTC three years later, below that high despite the much longer growth from early network history.
A steady total can hide offsetting transfers and entities moving across the 10 or 100 BTC boundaries. The earliest reading includes 50 BTC on January 3, 2009, but early balances and entity attribution are not directly comparable with the modern ownership structure.
The first observation records 50 BTC on January 3, 2009, within this balance range and equal to the original block subsidy. It is an early supply observation, not evidence of a market purchase.
No. It excludes the larger balance bands. To examine holdings above 10 BTC, the separate higher bands must also be considered.
Yes. Additions and reductions can offset each other, as can entries and exits at the band boundaries. A balance series alone cannot measure gross turnover.
